To provide a structure that can effectively prevent installation of a brake rotor to a rotating flange at a phase different from an initial installation phase.SOLUTION: A rotating flange 10 is constituted of: 4-thick wall parts 14 provided with hub bolt screw holes 15, respectively; and 4-thin wall parts 16 for connecting the thick wall parts 14 adjacent in a circumferential direction, and having a minimum diameter part with an outer diameter reduced most in the circumferential direction intermediate part and having the axial thickness dimension smaller than the thick wall part 14. Also, the 4-thin wall parts 16 are constituted of 2-small diameter thin wall parts 17 and 2-large diameter thin wall parts 18 arranged at the opposite side in the diameter direction of the rotating flange 10, respectively. Also, push bolt screw holes 19 having a pitch diameter larger than the outer diameter of the minimum diameter part of the small diameter thin wall part 17 are provided in the large diameter thin wall parts 18.SELECTED DRAWING: Figure 2
【課題】ブレーキロータを回転フランジに対し、初期取り付け位相とは異なる位相で取り付けることを有効に防止できる構造を実現する。【解決手段】回転フランジ10を、それぞれにハブボルト用ねじ孔15が設けられた4つの厚肉部14と、円周方向に隣り合う厚肉部14同士をつなぐとともに、周方向中間部に最も外径寸法が小さくなった最小径部を有し、かつ、厚肉部14よりも軸方向厚さ寸法の小さい4つの薄肉部16とから構成する。また、4つの薄肉部16を、それぞれが回転フランジ10の直径方向反対側に配置された2つの小径薄肉部17と2つの大径薄肉部18とから構成する。また、大径薄肉部18に、小径薄肉部17の最小径部の外径よりもピッチ円直径の大きい押しボルト用ねじ孔19を設ける。【選択図】図2
